information of said respective partial information, along a
reproduction time series in said main information; and a
controlling step for controlling said outputting device so as to
repeatedly perform said outputting operation with respect to the
same said main information and said order information.
According to the present invention, since a computer functions so
that the order information is outputted together with the main
information, even when the recording is started from the middle
part of the foregoing main information to be outputted upon
recording the foregoing outputted main information, it is possible
to record the main information so as to be reproduced in accordance
with the original composition order thereon.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Then, the preferred embodiments of the present invention will be
described with reference to the drawings. In respective embodiments
to be described below, the present invention is applied in a
contents distributing system including an outputting apparatus for
reproducing contents from a DVD (an optical disk having a recording
capacity several times as much as that of a conventional CD
(Compact Disc)), in which the contents are recorded, and
distributing the reproduced contents through the Internet lines and
a recording apparatus for recording the foregoing distributed
contents in a DVD-R (DVD-Recordable) that is a recordable DVD.
(1) First Embodiment
At first, a first embodiment of the present invention will be
explained with reference to FIGS. 1 to 11.
At the beginning, a whole configuration and a whole operation of a
contents distributing system according to the first embodiment will
be described with reference to FIG. 1. FIG. 1 is a block diagram
for showing a whole configuration of the content distributing
system.
As shown in FIG. 1, a contents distributing system S according to
the first embodiment is composed of: an outputting apparatus 10 for
outputting (distributing) contents (including reproducing control
information for controlling a reproduction manner (a reproduction
order, a reproduction speed or the like) of the foregoing contents)
through the Internet lines IN; and a recording apparatus 11 for
obtaining the foregoing outputted contents from the Internet lines
IN and recording it in the DVD-R.
Alternatively, the outputting apparatus 10 is composed of: a player
12 for reproducing the foregoing contents from the DVD, in which
the contents are recorded, and outputting it as a reproduction
signal Sd; and a transmission apparatus 13 as a distributing device
for applying a predetermined modulation processing or the like to
the foregoing reproduction signal Sd and outputting it to the
Internet lines IN.
Further, the recording apparatus 11 is composed of: a set top box
14 as a receiving obtaining device for obtaining the foregoing
outputted contents from the Internet IN and outputting it as a
recording signal Sr; and a recorder 15 as a recording device for
recording the foregoing outputted recording signal Sr in the DVD-R
by a method to be described later.
(A) Configuration and Operation of Player
Next, the detailed configuration and the operation of the player 12
according to the first embodiment will be explained with reference
to FIGS. 2 to 5.
FIG. 2 is a block diagram for showing a detailed configuration of
the player 12. Additionally, FIGS. 3 to 5 are diagrams for
explaining a format of the contents, which are included in the
reproduction signal Sd.
As shown in FIG. 2, the player 12 of the first embodiment is
composed of: a spindle motor 50 for rotating a DVD 72, in which the
contents are recorded, with a preset number of revolutions; a
driver 52; a phase comparator 51; a pick up 60; an RF (Radio
Frequency) amplifier 61; a clock extraction unit 62; a decoder 67;
and a CPU 68 as an outputting device and a changing device.
Here, the foregoing contents are compressed by a compression system
such as a so-called MPEG (Moving Picture Experts Group) system or
the like without relation to a time axis, in other words, by a
so-called variable bit rate.
Then, the operation of the player 12 will be explained below.
At first, the pick up 60 irradiates an optical beam B for
reproducing the information having a preset and fixed intensity on
the information recording surface of the DVD 72. Then, the pick up
60 generates an RF signal Sp in association with the contents,
which are recorded in the foregoing DVD 72, on the basis of its
reflection to output it to the RF amplifier 61.
Thus, the RF amplifier 61 applies a waveform forming processing, an
amplifying processing and the like to the foregoing RF signal Sp,
generates an amplified signal Sap and outputs it to the clock
extraction unit 62 and the decoder 67.
Then, the clock extraction unit 62 extracts a synchronization
signal Scl used for controlling the rotation of the spindle motor
50 from the foregoing amplified signal Sap and outputs it to the
phase comparator 51.
The phase comparator 51 compares the foregoing synchronization
signal Scl with a preset reference clock, which is a reference of
the foregoing rotation control, generates a phase difference signal
Scp indicating a phase difference thereof and outputs it to the
driver 52.
After that, the driver 52 generates a driven signal Ssd for
rotating the spindle motor 50 on the basis of the phase difference
signal Scp so that the phase difference shown by the foregoing
difference signal Scp becomes zero. Then, the driver 52 outputs the
generated driven signal Ssd to the foregoing spindle motor 50.
Thus, the spindle motor 50 rotates on the basis of the foregoing
driven signal Ssd, so that the DVD 72 rotates with the above preset
number of revolutions.
On the other hand, the decoder 67, in which the above described
amplified signal Sap is inputted, applies a preset demodulation
processing or the like to the foregoing amplified signal Sap,
generates the demodulation signal Sdc in association with the
contents recorded in the above described DVD 72, and outputs it to
the CPU 68.
The CPU 68 repeatedly outputs the foregoing demodulation signal Sdc
as the above described reproduction signal Sd to the transmission
apparatus 13 and to the Internet IN with respect to the same
contents. Simultaneously, the CPU 68 overall controls the
operations of the above described respective component members so
that they repeat the above described operations as the player
12.
Then, a format of the reproduced contents, which are included in
the above described reproduction signal Sd, will be explained with
reference to FIGS. 3 to 5.
The above described contents recorded in the DVD 72 are physically
composed so as to include a plurality of data sectors 20
illustrated in the top part of FIG. 3.
One of the data sectors 20 includes from the head point thereof: ID
information 21 including a sector address number showing a
reproduction position (a reproduction order) in the foregoing
contents of the data sector 20; an ID information error correction
code (IEC (ID Data Error correction Code)) 22 for correcting an
error of the forgoing ID information 21; an auxiliary data 23; data
24 comprising a picture, a sound itself or the like included in the
above contents; and an error detecting code (EDC) 25 for detecting
an error in the data 24. Further, a plurality of the data sectors
20 are continuously disposed, so that the above contents are
composed.
Then, as shown in the middle part of FIG. 3, in detail, the
foregoing ID information 21 is composed of: sector information 45
as several information with regard to the data sector 20, in which
the ID information 21 is included; and an address number 46 of the
above described sector.
Additionally, as shown in the lowest part of FIG. 3, the sector
information 45 is composed of: sector format information 47 as the
information representing a recording format in the DVD 72 (namely,
the information representing whether or not the format is a
so-called CLV (Constant Line Velocity) format, or the like);
tracking method information 48 as the information representing a
tracking system in the DVD 72 (namely, the information representing
whether or not the system is a so-called group tracking system, or
the like); reflection coefficient information 49 as the information
indicating a design value of the reflection coefficient of an
optical beam B in the DVD 72; an auxiliary area 80 in which no
information is included; area information 81 as the information
indicating a segment of the area on the DVD 72 in which the data
sector 20 thereof is recorded (namely, a segment to indicate
whether the data sector 20 thereof is recorded in the recording
area on the DVD 72 or it is recorded in the lead-in-area or the
like); data format information 82 as the information representing a
format of the data 24 included in the data sector 20 (namely, a
format to indicate whether the foregoing data 24 comprises a
picture or a sound itself or it comprises the information in the
connection area in a rewritable optical disk); and a recording
surface number 83 for indicating the number of the information
recording surface in which the data sector 20 is recorded (namely,
the information recording surface number of the DVD having not less
than two information recording surfaces).
Next, a configuration of an ECC (Error Correcting Code) block,
which is composed of a plurality of the above described data
sectors 20 on the DVD 72, will be explained with reference to FIG.
4.
Here, the foregoing ECC block is a collection of the data which is
a base unit of the error correction processing to be carried out in
the decoder 67 upon reproducing the contents from the DVD 72.
In the ECC block composed of a plurality of data sectors 20, a
plurality of data blocks 33 and a plurality of ECC inner codes (PI
(Parity In) codes ) 31 are included. The data block 33 is an each
data block which is obtained by dividing one data sector 20 for
every 172 bytes. Each ECC inner code 31 having 10 bytes length is
added to the end of each data block 33 in a data assembly which is
composed by aligning twelve lines of data blocks 33 in the vertical
direction (see a left portion in FIG. 4). The ECC block includes a
plurality of correction blocks 34, each of which is obtained by
adding each ECC inner code 31 to each data block 33.
In this case, twelve correction blocks 34, i.e., twelve lines of
the correction blocks 34 are equivalent to one data sector 20. One
ECC block 30 includes these correction blocks 34, which are
equivalent to sixteen data sectors 20, i.e., 192 lines of the
correction blocks 34.
Further, in the ECC block 30, the above 192 lines of the correction
blocks 34 are divided in the vertical direction for every byte from
the beginning with being aligned in the vertical direction and
sixteen ECC outer codes (PO (Parity Out) code) 32 are added to the
divided data, respectively. The foregoing ECC outer code 32 is a so
added to a portion of the ECC inner code 31 in the above described
correction block 34.
According to the above described configuration, one ECC block 30
including sixteen data sectors 20 is formed as shown in a right
portion of FIG. 4. In this case, a total amount of the information
included in one ECC block 30 is represented by the following
mathematical expression: (172+10) bytes.times.(192+16) lines=37,856
bytes. (Expression 1) In the above expression 1, an actual data 24
is represented by the following mathematical expression: 2,048
bytes.times.16=32,768 bytes. (Expression 2)
Additionally, in the ECC block 30 shown in FIG. 4, data of one byte
is represented by "D#.*". For example, "D1.0" represents the one
byte data disposed in the first line and the zero column and
"D190.170" represents the one byte data disposed in the 190th line
and the 170th column. Accordingly, the ECC inner codes 31 are
disposed on from the 172nd to the 181st lines and the ECC outer
codes 32 are disposed on from the 192nd to the 207th lines.
Further, one correction block 34 is continuously recorded on the
DVD 72.
The ECC block 30 is configured with including both of the ECC inner
code 31 and the ECC outer code 32 as shown in a right portion of
FIG. 4 so as to correct the data aligned in the horizontal
direction in the right portion of FIG. 4 by the ECC inner code 31
and to correct the data aligned in the vertical direction in the
right portion of FIG. 4 by the ECC outer code 32. In other words,
it becomes possible to correct the error doubly in the horizontal
direction and the vertical direction in the ECC block 30, which is
shown in the right portion of FIG. 4.
The above point is specifically described below. For example, even
if one correction block 34 (as described above, it includes one
line of the ECC inner code 31, i.e., the data, of which total
amount is 182 bytes, and it is continuously recorded on the DVD 72)
is completely destroyed by a scratch or the like of the DVD 72, the
data is destroyed only be one byte with respect to one column of
the EGC outer code 32 in the vertical direction. Accordingly, if
the error is corrected in the decoder 67 on the reproduction by
using the ECC outer code 32 in each column, it is possible to
accurately correct the error and reproduce the contents even when
one correction block 34 is completely destroyed.
Then, the actual recording format in the above described EIC block
30 on the DVD 72 will be explained with reference to FIG. 5.
Alternatively, in FIG. 5, the data represented by "D#.*"
corresponds to each data described in the right portion of FIG.
4.
As shown in the top part of FIG. 5, the ECC block 30 on the DVD 72
is divided in sixteen recording sectors 40, which are obtained by
aligning the ECC block 30 in the horizontal direction in a row for
every correction block 34 and interleaving it, to be recorded.
In this case, one recording sector 40 includes the information of
2,366 bytes (i.e., 37,856 bytes/16). The data sector 20 and the ECC
inner code 31 or the ECC outer code 32 are mixed in this one
recording sector 40. However, an ID information 21 in the data
sector 20 (see FIG. 3) is disposed on a head of respective
recording sectors 40.
Then, one recording sector 40 is divided into data 41 each having
91 bytes length and added to a header H, respectively. In this
state, the contents are recorded in the DVD 72 as one sync frame 42
obtained by so-called 8-16 modulating the recording sector 40 for
each data 41.
In this case, one sync frame 42 is composed of a header H' and data
43. Alternatively, the amount of the information in one sync frame
42 is represented by the following mathematical expression: 91
bytes.times.8.times.(16/8)=1,456 bytes. (Expression 3) The contents
are recorded in the DVD 72 with these sync frames 42 being
continuously disposed. In this case, one recording sector 40
includes twenty-six sync frames 42.
Since the contents are recorded in the DVD 72 in the recording
format, which is configured as described above, if 8-16
demodulation and deinterleaving are performed upon reproducing the
foregoing contents (see FIG. 5), the original ECC block 30 is
capable of being restored and it becomes possible to accurately
reproduce the contents due to the above described strong error
correction and output it to the transmission apparatus 13 as the
reproduction signal Sd.
Alternatively, the above described reproduction signal Sd to be
outputted to the Internet IN through the transmission apparatus 13
is outputted on the foregoing Internet IN with the recording
sectors 40 being aligned having the ID information 21, which is
shown a second part from the top in FIG. 5 as a head.
(B) Configuration and Operation of Recorder
Next, the detailed configuration and the operation of the recorder
15 according to the first embodiment will be explained with
reference to FIGS. 6 to 11.
FIGS. 6 to 8 show the configuration of the DVD-R in which the
contents are recorded by the recorder 15. FIG. 9 is a block diagram
showing the detailed configuration of the recorder 15. FIGS. 10 and
11 are flow chart or the like showing the recording processing in
the recorder 15.
At first, prior to explaining the operation of the recorder 15, the
configuration and the recording manner of the DVD-R in which the
contents to be outputted through the above described Internet IN
are recorded, will be explained with reference to FIGS. 6 to 8.
At first, with reference to FIG. 6, the structure of the DVD-R
according to the first embodiment will: be explained.
In FIG. 6, a DVD-R 1 rotated in a linear velocity fixed system
comprises a coloring DVD-R which comprises a color membrane 5 and
which is capable of writing the information once. In this DVD-R 1,
a groove track 2 which is a track to be recorded with the contents,
and a land track 3 for guiding the optical beam B such as a laser
beam or the like as the reproduced light or the recorded light to
the foregoing groove track 2 are formed.
Additionally, this DVD-R comprises: a protecting membrane 7 for
protecting the above groove track 2 and the land track 3; and a
metal deposition surface 6 for reflecting the optical beam B upon
reproducing the recorded information. A pre-pit 4 in association
with pre-information is formed in this land track 3. In this case,
the foregoing pre-pit 4 is formed in advance prior to shipping the
DVD-R 1.
Here, as the above described pre-information, an address number
showing a position on the DVD-R 1 to be recorded with the contents
(hereinafter, the address number recorded on the DVD-R 1 by using
the pre-pit 4 is referred to as a block address number) is recorded
by using the above described pre-pit 4.
Further, in the foregoing DVD-R 1, the groove track 2 is wobbled
with a frequency in association with the rotation rare of the
foregoing DVD-R 1. A synchronized signal for controlling the
rotation by a wobbling of this groove track 2 is recorded in
advance prior to shipping the DVD-R 1 as same as the above
described pre-pit 4.
Then, upon recording the above described contents in the DVD-R 1,
detecting a frequency of the wobbling of the groove track 2 by the
recorder 15 allows the above described synchronized signal to be
obtained so as to control the rotation of the DVD-R 1 with a
predetermined rotation rate and detecting the pre-pit 4 allows a
pre-information to be obtained in advance. The optimum output or
the like of the optical B as a recording light is set on the basis
of the obtained pre-information and a block address number or the
like representing a position on the DVD-R 1 to be recorded with the
contents is obtained. Then, the foregoing contents are recorded on
a recording position in association with the above described ID
information 21 to be outputted on the basis of this block address
number.
Upon recording the contents, the optical beam B is irradiated so
that a center of the optical beam B accords with a center of the
groove track 2. Then, recording pits in association with the
recording information are formed on the groove track 2 to record
the foregoing contents.
In this case, a size of an optical spot SP is set so that a portion
of the optical spot SP is irradiated not only on the groove track 2
but also on the land track 3 as shown in FIG. 6. After that, by
using a portion of the reflection lights of the optical soot SP
irradiated on this land track 3, the above described
pre-information is detected from the pre-pit 4 by a push-pull
method (a radial push-pull method by using an optical detector
divided by a dividing line, which is in parallel with a rotation
direction of the DVD-R 1) to obtain the foregoing pre-information.
Further, by using a portion of the reflection light of the optical
spot SP irradiated on the groove track 2, a wobbling signal is
detected from the groove track 2 and the synchronized signal or the
like for controlling the rotation is obtained.
In the next place, pre-information recorded in the DVD-R 1
according to the first embodiment in advance, rotation controlling
information and a recording format of the above described recording
information will be explained with reference to FIG. 7.
In FIG. 7, an upper part represents the recording format of the
recording information and a wave form in a lower part represents a
wobbling state of the groove track 2, which records the foregoing
recording information (namely, a plane view of the groove track 2).
An upward arrow between the recording information and the wobbling
state of the groove track 2 schematically represents a position in
which the pre-pit 4 is formed.
In FIG. 7, the wobbling state of the groove track 2 is represented
by larger amplitude than actual amplitude so as to be easily
understood and the recording information is recorded on a central
line of the foregoing groove track 2.
As shown in FIG. 7, the recording information to be recorded in the
DVD-R 1 according to the first embodiment is divided in advance for
every sync frame 42 as described above. Then, one recording sector
40 is formed as an information unit by twenty-six sync frames.
Further, the above described ECC block 30 is formed by sixteen
recording sectors 40.
Alternatively, one sync frame 42 has a 1488-fold (1488 T) length as
long as a unit length in association with a bit spacing
(hereinafter, referred to as T) which is defined by a recording
format upon recording the above described recording information.
Further, a synchronized information SY is recorded in a portion
having a length of 14T in the head of one sync frame 42 as the
above described header H' (see the lowest step of FIG. 5) to
synchronize upon recording for every sync frame.
On the other hand, the pre-information recorded in the DVD-R 1
according to the first embodiment is recorded for every sync frame
42. In the case of recording the pre-information by the pre-pit 4,
one pre-pit 4 is always formed on the land track 3 adjoining an
area in respective sync frames 42 in the contents, in which the
synchronized information SY is recorded, to indicate the
synchronized signal in the pre-information (hereinafter, the
synchronized signal in the foregoing pre-information is referred to
as a sync code so as to be distinguished from the above described
synchronized signal for controlling the rotation of the DVD-R 1).
At the same time, two pre-pits 4 or one pre-pit 4 are formed on the
land track 3 adjoining a first half portion in the foregoing sync
frame 42 other than the foregoing synchronized information SY to
indicate the contents of the recorded pre-information (i.e., a
block address number). Alternatively, with respect to the first
half portion in the foregoing sync frame other than the
synchronized information SY, there is a case that the pre-pit 4 is
not formed depending on the contents of the pre-information to be
recorded. Additionally, at a head sync frame 42 in one recording
sector 40 (an EVEN frame to be described later), three pre-pits 4
are always continuously formed in its first half portion.
Here, in the DVD-R 1 of the first embodiment, the pre-pit 4 is
formed only in an even-numbered sync frame 42 (hereinafter,
referred to as an EVEN frame) or only in an odd-numbered sync frame
42 (hereinafter, referred to as an ODD frame) in one recording
sector 40, so that the pre-information is recorded. In other words,
in the case that the pre-pit 4 is formed in the EVEN frame in FIG.
7 (it is indicated by a full line upward arrow in FIG. 7), the
pre-pit 4 is not formed in the ODD frame adjoining the EVEN
frame.
Additionally, considering a relation between the wobbling of the
groove track 2 and the position of the pre-pit 4, the pre-pit 4 is
formed in a position of the largest amplitude in the foregoing
wobbling.
In order to specifically explain a relation between the contents of
the pre-information and a position in which the pre-information is
formed in the pre-pit 4, the pre-pit 4 formed on the land track 3
adjoining the area in which the synchronized information SY is
recorded is defined as "a pre-pit B2" and the pre-pits 4 formed on
the land track 3 adjoining the first half portion in the sync frame
other than the synchronized information SY are defined as "a
pre-pit B1" and "a pre-pit B0" from the head thereof. Then, as
shown in the following table 1, the pre-pits B2 to B0 are
completely formed in a place in association with a sync code in the
EVEN frame in the head of one recording sector and the pre-pits B2
and B1 are only formed in a place in association with a sync code
in the ODD frame. Further, the pre-pit B2 and the pre-pit B0 are
only formed in a place in association with data "1" as the
pre-information other than the sync code and the pre-pit B2 is only
formed in a place in association with data "0" as the
pre-information other than the sync code.
[Table 1]
TABLE-US-00001 TABLE 1 Pre-pit Contents of information B2 B1 B0
Sync code of EVEN frame 1 1 1 Sync code of ODD frame 1 1 0
Pre-information data "1" 1 0 1 Pre-information data "0" 1 0 0
On the other hand, the groove track 2 is wobbled with a
predetermined wobbling frequency of about 140 kHz (a frequency such
that one sync frame 42 is equivalent to eight waves of the
variation waveform of the groove track 2) across all sync frames
42. Alternatively, in the recorder 15, detecting the foregoing
predetermined wobbling frequency allows the above described
synchronized signal, which controls the rotation of the spindle
motor 50 for rotating the DVD-R 1 to be described later, to be
detected.
Then, the contents of the block address number recorded as the
above described pre-information will be explained together with a
whole configuration of the DVD-R 1 with reference to FIG. 8.
As shown in the upper part in FIG. 8, the DVD-R 1 is totally
composed of, from its inner radius side: a controlling information
area CD in which the information to be used as a controlling
information upon recording the contents is recorded in advance; a
lead-in area L1 in which start information or the like to be used
upon starting the reproduction of the contents recorded in the
DVD-R 1 is recorded; a file system Information area FA in which the
information indicating a hierarchical structure of respective data
included in the recorded contents is recorded; a recording area DA
in which the content itself is Included in actual; and a lead-out
area L0 in which termination information or the like to be used
upon terminating the reproduction of the contents recorded in the
DVD-R 1 is recorded.
In this case, the above described lead-in area L1, the file system
information area FA and the lead-out area LO are formed in
association with the foregoing contents after the contents have
been recorded in the DVD-R 1.
Alternatively, as shown in the lower part in FIG. 8, a sector
address number in the above described ID information 21 in the
contents to be recorded in a head of the lead-in area L1 is defined
as "022FA0h ("h" indicates a hexadecimal and so forth). Further, it
is standardized that a sector address number in the above described
ID information 21 in the contents to be recorded in a head of the
file system information area FA is defined as "030000h" as shown in
the lower part of FIG. 8.
On the other hand, the block address numbers recorded in advance as
the above described pre-information by the pre-pit 4 are recorded
so that they are recorded in ascending order from the innermost
radius side of the controlling information area CD as the lowest
value to the outer radius side of the DVD-R 1 as shown in a
longitudinal axis of FIG. 8.
In this case, it is standardized that a relation between the block
address number as the pre-information and the sector address number
in the contents is defined so that the former should be 10h-fold as
much as the latter.
In the next place, the detailed configuration and the operation of
the recorder 15 in the recording apparatus 11 for recording the
contents outputted from the above described outputting apparatus 10
to the above described DVD-R 1 through the Internet IN will be
described with reference to FIGS. 9 to 11.
Alternatively, the recorder 15 of the first embodiment can not only
record the contents in the DVD-R 1 but also reproduce them from the
DVD-R 1.
Additionally, in the block diagram of FIG. 9, with respect to the
same composing members as those of the block diagram shown in FIG.
2, the same reference numerals are given and the detailed
explanation thereof is omitted.
As shown in FIG. 9, the recorder 15 of the first embodiment is
composed of: a spindle motor 50 for rotating the DVD-R 1 in which
the contents are recorded with a pre-set rotation number; a driver
52; a phase comparator 51; a pick up 60; an RF amplifier 61; a band
pass filter 69; a wobbling detecting unit 63; an LPP (Land Pre Pit)
detecting unit 64; an LPP decoder 66; a decoder 67; a CPU 68
including a memory 68m; an address detecting circuit 70; and an
interface unit 71.
At first, the operation for reproducing the contents, which have
been already recorded in the DVD-R 1, will be explained below.
In the above reproduction, the spindle motor 50, the driver 52, the
phase comparator 51, the pick up 60, the RF amplifier 61, the
decoder 67 and the CPU 68 generates the demodulation signal Sdc in
association with the contents recorded In the rotating DVD-R 1 by
performing the same operation as that of the above described player
12 to output the generated demodulation signal Sdc to an amplifier
(not shown) or the like in the exterior through the interface 71 as
an output signal So.
In this case, with respect to the synchronized signal Scl to be
compared with a reference clock in the phase comparator 51, a band
pass signal Sbp including the synchronized signal in association
with the frequency of the wobbling of the above described groove
track 2 is extracted from the amplified signal Sap by using the
band pass filter 69. Further, the above described synchronized
signal Scl having the frequency of 140 kHz in association with the
above wobbling is generated from the foregoing extracted band pass
signal Sbp.
In the next place, the operation for recording the contents
included in the recording signal Sr, which is received and
outputted in the set top box 14, in the DVD-R 1 will be explained
below.
At first, the interface processing which is pre-set in the
interface unit 71 is applied to the recording signal Sr Inputted in
the recorder 15 (the recording signal Sr including the content to
be recorded in the DVD-R 1). Then, the recording signal Sr is
accumulated in the memory 68m in the CPU 68 as a processing
recording signal Sri as well as it is outputted to the address
detecting circuit 70.
On the other hand, prior to recording the contents, the pick up 60
irradiates the optical beam B to the pre-pit 4 on the DVD-R 1,
generates the RF signal Sp in association with the foregoing
pre-pit 4 and outputs it to the RF amplifier 61.
Thus, the RF amplifier 61 applies the processing such as the
amplifying processing or the like to the foregoing the RF signal
Sp, generates the amplified signal Sap and outputs it to the band
pass filter 69.
Then, the Land pass filter 69 generates the synchronized signal in
association with the frequency of the wobbling in the above
described groove track 2 and the band pass signal Sbp including the
block address number in association with the above described
pre-pit 4 from the amplified signal Sap to output them to the above
wobbling detecting unit 63 and the LPP detect Ing unit 64.
In the next place, the above wobbling detecting unit 63 generates
the synchronization signal Scl having a frequency in association
with the above wobbling from the foregoing band pass signal Sbp as
same as that in the reproduction of the contents and outputs it to
the phase comparator 51 and a cross talk removing unit 65.
Thus, the phase comparator 51 and the driver 52 rotate the DVD-R 1
with a pre-set rotation number by the same operation as that in the
case of the above described player 12.
On the other hand, the LPP detecting unit 64, in which the band
pass signal Sbp is inputted, detects the signal component in
association with the above block address number from the foregoing
band pass signal Sbp and outputs it to the cross talk removing unit
65 and the LPP decoder 66 as an LPP signal Slpp.
Then, the cross talk removing unit 65 removes the cross talk
component caused by the pre-pit 4 from the synchronized signal Scl
on the basis of the LPP signal Slpp, generates a recording clock
signal Swck having a frequency as a reference upon recording the
contents and outputs it to an encoder 91.
Additionally, the LPP decoder 66 analyzes the contents of the LPP
signal Slpp and generates the block address number (namely, the
block address number indicating a position on the DVD-R 1 on which
the optical beam B is irradiated now) signal Sdl to output the
generated signal Sdl to the CPU 68.
In the next place, the address detecting circuit 70 extracts the
sector address number in the ID information 21 in each of the above
recording sectors 40, which is included in the foregoing processing
recording signal Sri, from the foregoing processing recording
signal Sri to output the extracted sector address number to the CPU
68 as an address signal Sadd.
Then, the CPU temporally stores the foregoing processing recording
signal Sri in the memory 68m and compares the contents of the
address number signal Sdl with the contents of the address signal
Sadd to output the processing recording signal Sri to the encoder
91 at the timing having a corresponding relation in which the both
signals are pre-set (namely, the latter is 10h-fold as much as the
former).
Thus, the encoder 91 applies the pre-set modulation processing or
the like to the processing recording signal Sri on the basis of the
above recording clock signal Swck and generates a modulation signal
Se to output the generated modulation signal Se to a power
controlling unit 92.
Then, the power controlling unit 92 generates a power controlling
signal Spc and outputs it to a laser driving unit 93 so as to
demodulate the intensity of the optical beam B for recording so
that the optical beam B corresponds to the modulation signal Se on
the basis of the controlling signal Sc from the CPU 68.
Then, the laser driving unit 93 generates a driving signal Sld for
driving a semiconductor laser (not shown) in the pick up 60 for
emitting the foregoing optical beam B and outputs the generated
driving signal Sld to the foregoing pick up 60 so that the optical
beam B is irradiated to the above groove track 2 on the DVD-R 1
with the changed intensity shown by the foregoing power controlling
signal Spc.
According to the above described series of the operation, as the
recorder 15, the laser driving unit 93 is capable of recording the
contents (a recording sector 40) in association with a sector
address number, which is included in the foregoing address signal
Sadd, in a recording position on the DVD-R 1 in which the address
number signal Sdl in association with the address signal Sadd is
obtained.
In the next place, the total flow of the recording processing for
recording the above described contents in the DVD-R 1 will be
described in detail with reference to FIGS. 10 and 11. The
recording processing to be described below comprises the processing
to be mainly controlled and processed by the CPU 68.
As shown in FIG. 10, in the foregoing recording processing, at
first, it is monitored whether or not the address signal Sadd is
inputted, so that it is confirmed that the input of the recording
signal Sr is started and the sector address number of a head in the
inputted contents is detected (step S1).
In the next place, the irradiation position of the optical beam B
for recording is moved to a position of the block address number
(this block address number is referred to as "T" and it is stored
in another memory (not shown) in the CPU 68) having the above
corresponding relation with the above detected sector address
number (step S2) Here, it is assumed that the foregoing irradiation
position is moved to a position represented by the mark "" in FIG.
11 by this processing.
Further, in this state, it is monitored whether or not a head of
the ECC block 30 in the contents is detected (step S3). If it is
not detected (step S3; NO), the monitor of the contents has been
continued. On the other hand, if the foregoing head is detected
(step S3; YES) then, filling the inputted contents in the memory
68m is started (step S4).
In the next place, it is monitored whether or not the memory 68m is
filled (step S5). If it is not filled (step S5; NO), the filling
has been continued. On the other hand, if it is filled (step S5;
YES), the recording of the contents in the foregoing memory 68m in
the DVD-R 1 is started (step S6).
In the recording processing in the consents in this step S6, as
shown in a third part from above in FIG. 11, the contents are
recorded toward the outer radius of the DVD-R 1 from the position
of T in the block address number detected in the step S2. As the
foregoing recording manner of the foregoing content in this case,
as shown in the lowest part in FIG. 5, the contents have been
recorded for every sync frame 42.
Alternatively, as shown in FIG. 1, in the foregoing recording
processing, the above synchronized information SY is also formed
and recorded every when one recording sector 40 is formed and
recorded.
Then, in the recording processing in the step S6, it is monitored
whether or not the last (the outermost radius side) block address
number on the DVD-R 1 is detected (step S7).
Further, if the last block address number is not detected (step S7;
NO), the recording processing has been continued since the
recording of the contents is still capable of being continued in
the recording area DA in the DVD-R 1. On the other hand, if the
last block address number is detected (namely, if the contents
having the corresponding sector address number have been recorded
till the position of the block address number in the outermost
radius side in the recording area DA (step S7; YES), then, the
recording is temporarily stopped (step S8). Further, the
irradiation position of the optical beam B is moved to the
innermost radius side of the recording area DA (step S9) and the
recording processing, which is stopped after The irradiation
position of the optical beam B is moved, is restarted (step S10).
According to this processing, as shown in a forth part from above
in FIG. 11, the contents have been continuously recorded from the
innermost radius side of the recording area DA.
In the next place, after the recording processing is restarted, it
is monitored whether or not the block address number "T", which is
stored when the recording is started in the above step S2, is
detected again (step S11).
Then, if the detected block address number is not "T" (step S11;
NO), since the contents have not been recorded till a recording
position shown by the mark "" in FIG. 11 (namely, the recording of
the contents is not completed in the DVD-R 1), the recording
processing has been continuously performed toward the outer radius
side (step S10). On the other hand, if the block address number "T"
is detected (step S11; YES), the recording is terminated since the
recording of the contents in the DVD-R 1 has been completed (step
S12). Further, as shown form the lowest part to the third part from
the lowest part in FIG. 11, lead-out data LOD as termination
information or the like to be recorded in lead-out area LO, lead-in
data LID as start information or the like to be recorded in a
lead-in area LI and file system information FAD as file information
or the like to be recorded in a file system information area FA are
recorded in an area on the DVD-R 1 in association with the data or
the information, respectively (step S13), so that the all recording
processing has been terminated.
In this case, according to the file system forming processing in
the step S13, a file system is formed when a head of the contents
is not a sector address number in which the recording is started (a
sector address number in association with a position represented by
the mark "" in FIG. 11) but it is a sector address number
corresponding to the innermost radius side of the recording area
DA. Further, describing that a sector address number corresponding
to (a sector address number in association with the foregoing mark
""-1h) is connected to a sector address number in association with
the foregoing mark "", the file system is formed.
After the above described recording processing has been terminated,
as shown in the lowest part in FIG. 11, the contents starting from
the mark "" position in FIG. 11 (corresponding to the block address
number "T") have been continuously recorded till the outermost
radius side of the recording area DA. Then, it is continuously
recorded from the innermost radius side of the recording area DA.
When it is recorded in the foregoing mark "" position, the series
of the recording of the content has been terminated.
As described above, according to the operation of the contents
distributing system S of the first embodiment, the sector address
number in the contents to be recorded is distributed together with
the contents, so that the contents are capable of being recorded so
as to be reproduced on the code of the original configuration order
even when the recording is started from the midstream of the
foregoing contents to be distributed upon recording the foregoing
contents in the DVD-R 1.
Alternatively, since the contents and the sector address number are
distributed through the Internet lines IN, it is possible to
rapidly and reliably distribute the contents and the sector address
number even when the outputting apparatus 10 and the recording
apparatus 11 are placed with a distance.
Further, the contents recorded in the DVD 72 is reproduced and
distributed as it is and the reproduction controlling information
in the foregoing contents is also distributed together with the
sector address number in the recording apparatus 11, so that it is
possible to reproduce the contents in various manners on the basis
of the foregoing reproduction controlling information upon
reproducing the contents after outputting them to the recording
apparatus 11 and recording them in the DVD-R 1.
Alternatively, according to the above described first embodiment,
the case that the Internet lines IN is used as a circuit to connect
the outputting apparatus 10 and the recording apparatus 11 is
explained. However, other than this case, the outputting apparatus
10 and the recording apparatus 11 may be connected by any one of or
not less than two of a cable television circuit, a satellite
broadcasting circuit and around-based digital broadcasting
circuit.
As a recording medium on the recorder 15, a DVD-RW
(DVD-Re-Recordable) capable of writing plural times or a DVD-RAM
(DVD-Random Access Memory) may be used in addition to the DVD-R 1.
Further, as a recording medium which is filled in the player 12,
the DVD-R, the DVD-RW or the DVD-RAM, which has been already
recorded, may be used in addition to the DVD 72 for reproducing
only.
(II) Second Embodiment
Next, a second embodiment, which is another embodiment according to
the present invention, will be explained with reference to FIGS. 12
to 14.
FIG. 12 is a flow chart for showing a reproduction processing of a
player of the second embodiment of the present invention. FIG. 13
is a diagram for showing a recording processing of a recorder of
the second embodiment. FIG. 14 is a flow chart for showing a
reproduction processing of the foregoing recorder according to the
second embodiment.
In the above described first embodiment, the case is described that
the contents recorded in the DVD 72 are distributed as it is
together with the sector address number to be recorded in the DVD-R
1. However, according to the second embodiment to be described
below, the contents are distributed after a so-called illegal copy
preventing processing is applied to protect the contents, which is
illegally obtained and copied between the outputting apparatus and
the recording apparatus, from being illegally reproduced.
At first, a reproduction processing of the contents to be carried
out in a player of the second embodiment will be explained with
reference to FIG. 12.
It is assumed that CCI (Copy control Information) data, which is
controlling information for regulating the numbers of times of
recopy after the foregoing contents are copied once, is included in
the contents to be reproduced by the player according to the second
embodiment by a publicly known method such as a water mark
technique or the like. In this case, as the contents of the
foregoing CCI data, a copy prohibition data for prohibiting a copy
(hereinafter, the foregoing copy prohibition data is referred to as
NC (Never Copy) information), recopy prohibition data for
prohibiting a copy more than once (hereinafter, the foregoing
recopy prohibition data is referred to as NMC (No More Copy)
information), permission data for permitting a copy only once
(hereinafter, the foregoing permission data is referred to as CO
(Copy Once) information) and permission data for permitting a copy
in any numbers of times (hereinafter, the foregoing permission data
is referred to as CF (Copy Free) information) are considered.
As shown in FIG. 12, at first, the repeating reproduction
processing is started as same as the first embodiment in the
reproduction processing in the player of the second embodiment
(step S15). Then, the CCI data included in the foregoing contents
to be reproduced is detected and it is determined whether or not
the content of the CCI data is the NC information (step S16).
If it is the NC information (step S16; YES), an offset value for
uniformly shifting the sector address number in the contents in the
step S24 to be described later is shifted to the foregoing step S24
as "16h" (step S17).
On the other hand, in the determination of the step S16, if the CCI
data is not the NC information (step S16; NO), then, it is
determined whether or not the content in the foregoing CCI data is
the NMC information (step S18) If it is the NMC information (step
S18; YES), the above offset value is shifted to the step S24 as
"32h" (step S19).
On the other hand, in the determination in the step S18, if the CCI
data is not the NMC information (step S18; NO), then, it is
determined whether or not the content of the foregoing CCI data is
the CO information (step S20)
Further, it is the CO information (step 20; YES), the above offset
value is shifted to the step S24 as "48h" (step S21).
On the other hand, in the determination of the step S20, if the CCI
data is not the CO information (step S20 NO), then, it is
determined whether or not the content of the foregoing CCI data is
the CF information (step S22).
Further, if it is the CF information (step S22; YES), the above
offset value is shifted to the foregoing step S24 as "64h" (step
S23).
On the other hand, in the determination of the step S22, if the CCI
data is not the CF information (step S22; NO), there is a
possibility such that the CCI data is tampered, so that the
reproduction processing itself is stopped so as to protect the
illegal copy.
If each offset value is set (steps S17, S19, S21, S23), a value
such that the offset value is added to each sector address number
included in the contents is determined as a new sector address
number (step S24), then, the contents including the new sector
address number are outputted to the Internet lines IN (step
S25).
Further, it is determined whether or nor the reproduction
Processing of the all content is completed (step S26). If it is not
completed (step S26; NO), the processing returns to the step S26 to
continue the output of the content. On the other hand, if it is
completed (step 26; YES), the reproduction processing is completed
as it is.
Then, a recording manner in the case that the contents outputted
from the outputting apparatus of the second embodiment are recorded
in the DVD-R 1 by the same recording processing as that of the
first embodiment (see FIG. 10) will be explained with reference to
FIG. 13.
In the case that the contents, which are reproduced and outputted
by the reproduction processing shown in FIG. 12, are recorded in
the DVD-R 1 as same as the recorder 15 of the first embodiment, the
sector address number in the content is uniformly shifted as
described above, so that, according to the recording processing as
a result thereof, the contents are recorded as same as the first
embodiment with an unrecorded portion N with a length ND is
remained in a head of a recording area DA as shown in FIG. 13.
In this case, the length ND of the unrecorded portion N becomes the
length equivalent to the length of sixteen sector address numbers
when the offset value on the reproduction is "16h". Further, when
the offset value on the reproduction is "32h", it becomes the
length equivalent to the length of thirty-two sector address
numbers, when the offset value on the reproduction is "48h", it
becomes the length equivalent to the length of forty-eight sector
address numbers and when the offset value on the reproduction is
"64h", it becomes the length equivalent to the length of sixty-four
sector address numbers.
In this case, the foregoing unrecorded portion N is an obstacle
upon reproduction, so that, for example, dummy data comprising
zero-data is recorded in the unrecorded portion N in actual and the
foregoing unrecorded portion N becomes the dummy data recorded
portion N in the last processing of the step S13 in the above
recording processing.
In the next place, the processing for reproducing the contents
recorded in the DVD-R 1 in the recorder of the second embodiment
while providing the illegal copy protection processing as described
above will be explained with reference to FIG. 14.
In the reproducing processing in the foregoing recorder, at first,
a sector address number in a headmost position of the contents
recorded in the DVD-R 1 is detected (step S25). Here, it is assumed
that the foregoing detected sector address number is "AD" (see the
lowest part of FIG. 13).
Then, it is determined whether or not the foregoing 10 detected
sector address number "AD" corresponds to the block address number
in the outermost radius side of the file system information area FA
in the SVS-R1 (step S26) In this case, the block address number of
the foregoing outermost radius side is defined as "T2".
Further, if the sector address number "AD" and the block address
number "T2" are in the original corresponding relation (namely, the
sector address number "AD" is ten-times as much as the block
address number "T2" in hex)(step S26; YES), it is perceived that
the unrecorded part N does not exist in the DVD filled in the
recorded of the second embodiment at the present time. Therefore,
in this case, the foregoing DVD is deemed as a so-called original
DVD for reproducing only, so that the processing shifts to the
reproduction processing as it is (step S36).
On the other hand, if the sector address number "AD" and the block
address number "T2" are not in the original corresponding relation
in the determination of the step S26 (step S26; NO), then, it is
determined whether or not the sector address number "AD" and the
value obtained by adding "16h" to the block address number "T2" are
in the original corresponding relation (step S27).
Then, if the sector address number "AD" and the value obtained by
adding "16h" to the block address number "T2" are in the original
corresponding relation (step S27; YES), it is deemed that the
contents in association with the NC information are copied at this
point of time. However, the copying of the NC information is an
illegal behavior, so that the processing shifts to the processing
for notifying a user that the content is not reproduced (step S29).
After that, the reproduction processing is terminated.
In the next place, if the sector address number "AD" and the value
obtained by adding "16h" to the block address number "T2" are not
in the original corresponding relation in the determination of step
S27 (step S27; NO), then, it is determined whether or not the
sector address number "AD" and the value obtained by adding "32h"
to the block address number "T2" are in the original corresponding
relation (step S30).
If the sector address number "AD" and the value obtained by adding
"32h" to the block address number "T2" are in the original
corresponding relation (step S30; YES), then, it is determined
whether or not the CCI data in the content, which is detected at
the present time, is the NMC information (step S31).
Thus, if the CCI data is the NMC information (step S31; YES), it is
determined that the length of the unrecorded portion N and the
content of the CCI data are in a normal relation. As a result, the
processing shifts to a normal reproduction processing (step
S36).
On one hand, if the CCI data is not the NMC information in the
determination of the step S31 (step S31; NO), it is deemed that
there is a strong possibility that the length of the unrecorded
portion N and the content of the CCI data are not in the normal
relation and the contents in the process of the reproduction at the
present time are illegally copied. As a result, the user is
notified that the contents are not reproduced (step S29) and the
reproduction processing is terminated.
On the other hand, the sector address number "AD" and the value
obtained by adding "32h" to the block address number "T2" are not
in the original corresponding relation (step S30; NO), then, it is
determined whether the sector address number "AD" and the value
obtained by adding "48h" to the block address number "T2" are not
in the original corresponding relation (step S32).
Further, if the sector address number "AD" and the value obtained
by adding "48h" to the block address number "T2" are in the
original corresponding relation (step S32; YES), then, it is
determined whether or not the above CCI data is the CO information
(step S33).
Thus, if the CCI data is the CO information (step S33; YES), it is
deemed that the length of the unrecorded portion N and the content
of the CCI data are in the normal relation. As a result, the
processing shifts to a normal reproduction processing (step
S36).
On one hand, if the CCI data is not the CO information in the
determination of the step S31 (step S33; NO), it is deemed that
there is a strong possibility that the length of the unrecorded
portion N and the content of the CCI data are not in the normal
relation and the contents in the process of the reproduction at the
present time are illegally copied. As a result, the user is
notified that the contents are not reproduced (step S29) and the
reproduction processing is terminated.
On the other hand, if the sector address number "AD" and the value
obtained by adding "48h" to the block address number "T2" are not
in the original corresponding relation (step S32; NO), then, it is
determined whether or not the sector address number "AD" and the
value obtained by adding "64h" to the block address number "T2" are
not in the original corresponding relation (step S34).
Further, if the sector address number "AD" and the value obtained
by adding "64h" to the block address number "T2" are in the
original corresponding relation or not (step S34; YES), then, it is
determined whether or not the CCI data in the contents detected at
the present time is the CF information (step S35).
Thus, if the CCI data is the CF information (step S35; YES), it is
deemed that the length of the unrecorded portion N and the content
of the CCI data are in the normal relation. As a result, the
processing shifts to a normal reproduction processing (step
S36).
On one hand, if the CCI data is not the CF information in the
determination of the step S35 (step S35; NO), it is deemed that
there is a strong possibility that the length of the unrecorded
portion N and the content of the CCI data are not in the normal
relation and the contents in the process of the reproduction at the
present time are legally copied. As a result, the user is notified
that the contents are not reproduced (step S29) and the
reproduction processing is terminated.
On the other hand, if the sector address number "AD" and the value
obtained by adding "64h" to the block address number "T2" are not
in the original corresponding relation in the determination of the
step S34 (step S34; NO), it is deemed that there is a strong
possibility that the contents in the process of the reproduction at
the present time are illegally copied. As a result, the user is
also notified that the content is not reproduced (step S29) and the
reproduction processing is terminated.
Further, in the reproduction processing (step S36), it is monitored
whether or not all the contents are completely reproduced (step
S37). If it is not completed (step S37; NO), the reproduction has
been continued till it is completed. If it is completed (step S37;
YES), the reproduction processing is terminated as it is.
As described above, according to the contents distributing system
of the second embodiment, the CCI data is included in the contents
in addition to the effect of the operation by the contents
distributing system S of the first embodiment and each sector
address number is uniformly changed in association with the content
of the foregoing CCI data. Further, the foregoing changed sector
address number is outputted to the recording apparatus together
with the content. Upon reproducing the contents recorded in the
DVD-R 1 by the recording apparatus, the contents are reproduced
after confirming a combination of the foregoing CCI data and the
changed sector address number, so that it is possible to prevent
the contents, which are illegally copied, from being illegally
reproduced.
Alternatively, according to the above described second embodiment,
the configuration such that the sector address number on a starting
position on the DVD-R 1 is offset is explained. However, in
addition to this, the sector address number may be offset upon
transmission.
(III) Third Embodiment
In the next place, a third embodiment, which is another embodiment
according to the present invention, will be explained with
reference to FIG. 15.
Alternatively, FIG. 15 is a flow chart for showing the recording
processing in a recorder according to the third embodiment.
According to the above described first embodiment, it is explained
that the contents recorded in the DVD 72 are distributed together
with the sector address number as it is and the contents are
recorded in a position of the block address number in association
with the DVD-R 1. However, according to the third embodiment to be
described below, the recording of the contents are started from a
head of the recording area DA in the DVD-R 1 having no relation to
the content of the sector address number to be distributed.
In the next place, the content recording processing to be carried
out in the recorder according to the third embodiment will be
explained with respect to FIG. 15.
According to the recording processing of the third embodiment, at
first, it is determined whether or not the distribution of the
contents from the outputting apparatus is started (step S40). If it
is not distributed (step S40; NO), the user may wait until it is
distributed. On the other hand, if the distribution is started
(step S40; YES), a head sector address number in the foregoing
distribution is stored in a memory (not shown) in the CPU 68 (step
S41) so that the contents distributed in the memory 68m have been
accumulated.
Then, if the contents have been accumulated up to a preset amount
of accumulation, then, the sector address number in the foregoing
accumulated contents is converted in ascending order from a
starting point, i.e., the sector address number in association with
a head of the recording area DA (specifically, "30000h") (step
S42).
In the next place, it is determined whether or not the reproduction
controlling information for controlling the reproduction manner of
the foregoing contents (more specifically, for example, a so-called
PGCI (Program Chain Information) or the like in the DVD standard)
is included in the foregoing accumulated contents (step S43).
Further, if the reproduction controlling information is included in
the foregoing accumulated contents or not (step S43; YES), the
sector address number included in this reproduction controlling
information is converted so as to correspond to the changed sector
address number in the above step S42 (step S44). Then, the
processing shifts to the step S45.
On the other hand, if the reproduction controlling information is
not included in the contents in the step S43 (step S43; NO), the
processing shifts to the step S45 as it is.
Then, in the step S45, the contents, which are distributed (steps
S40; YES) and of which sector address number is converted (step
S42; S44), are recorded from the head of the recording area DA in
the DVD-R 1 in sequence (step S45).
Further, it is monitored whether or not the contents in association
with the sector address number stored in the step S41 during the
foregoing recording are distributed again (step S46). If it is not
distributed again (step S46; NO), the processing returns to the
step S42 so as to repeat the above described operation with respect
to the contents which have been continuously distributed. On the
other hand, if the contents including the same recorded contents
are distributed again (step S46; YES), it is deemed that a series
of recording of the contents is terminated, so that the recording
is terminated (step S47). Further, as well as the step S13 in FIG.
10 according to the first embodiment, lead-out data LOD, lead-in
data LID and file system information FAD are recorded in an area on
the DVD-R 1 in association with the data or the information,
respectively (step S48) and the all recording processing is
terminated.
As described above, according to the processing of the recorder of
the third embodiment, the contents are recorded while converting
the content of the reproduction controlling information on the
basis of the sector address number which has been repeatedly
distributed, so that it is possible to record the contents so as to
be reproduced by the original reproduction manner from the head of
the DVD-R 1.
Alternatively, a program in association with the above described
recording processing or the reproduction processing is recorded in
an information recording medium such as a flexible disk or a hard
disk and this recorded program is executed by a personal computer
or the like, so that it may be possible to make the foregoing
personal computer function as a recorder or a player in respective
embodiments.
Additionally, according to the above described respective
embodiments, the case is explained such that the recording sectors
40 are aligned from the ID information 21 shown in a second part
from the top in FIG. 5 as a head in the reproduction signal Sd to
be outputted from the outputting apparatus 10 to the recording
apparatus 11 through the Internet IN. However, in addition to this,
the reproduction signal Sd may be formed in a manner shown a second
part from the bottom or the lowest part in FIG. 5 (namely, the
reproduction signal Sd is formed in a manner equivalent to the
manner of the RF signal) so that this reproduction signal Sd is
outputted to the Internet IN.
Further, a transmission rate upon outputting the reproduction
signal Sd from the outputting apparatus 10 to the recording
apparatus 11 may be determined so that the reproduction signal Sd
is capable of being transmitted with a high speed not less than
double speed.
The invention may be embodied in other specific forms without
departing from the spirit or essential characteristics thereof. The
present embodiments are therefore to be considered in all respects
as illustrative and not restrictive, the scope of the invention
being indicated by the appended claims rather than by the forgoing
description and all changes which come within the meaning and range
of equivalency of the claims are therefore intended to be embraces
therein.
